IMPROVEMENT IN MOUTH-PIECES FOR GAS-RETORTS.

Specification forming part of Letters Patent No. 166,131, dated July 27,1575; application filed June 28, 1875.

To all whom it may concern Be it known that I, PETER MUNZINGER, of thecity of Philadelphia and State of Pennsylvania, have invented certainImprovements in the Construction of Mouth-Pieces for Gas- Betorts, ofwhich the following is a specification:

The invention consists in the combination, with a retort mouth-piece, ofa knife-edge contact-piece, a lid or cover, and a guard for theprotection of the knife-edge contact-piece. It also consists in thecombination, with a retort mouth-piece, of a lid or cover, an eccentricwhich turns in the loose end of a pivoted or hinged bar, and across-bar.

Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is avertical section through the line 1 2, Fig. 1. Fig. 4 is a plan view ofFig. 3, the lid being removed.

A is a retort mouth-piece, and B a flange by which it is attached to theretort. O is a knife-edge projection around the mouth-piece, againstwhich the lid D is applied. Its purpose, when in contact with the lid,is to make a perfectly close gas-tight joint. E is a flange at the endof the mouth-piece, or an extension It extends a suitable distancebeyond the plane of the knife-edge (J, to guard and protect it frominjury by contacting with the implements employed in charging andoperating the retort.

G is an eccentric, a cam, or any curved surface capable of producing avariable pressure, pivoted in the loose end of the slotted bar H, whichis hinged in the jaws 1 of the mouthpiece. When the lid D is in placeagainst the knife-edge O, and the hinged cross-bar J is turned againstthe lid, its end or takes into the slot of the bar H, and is operated onby the cam G, the pressure exerted depending on the curve of theeccentric or cam and the inclination of its handle K. A screw, L, whichpasses through the cross-bar J, afi'ords additional pressure by pressingagainst the center of the lid. To open the lid the eccentric isreversed, and the bar H turned from the end of the bar J, which is thenthrown back.

I claim as my invention- 1. The combination of the retort mouthpiece A,knife-edge contact-piece (J, lid D, and the guard E, as shown anddescribed.

2. The combination of the retort mouthpiece A, lid D, eccentric G,hinged bar H, and the cross-bar J, as shown and described.

In testimony whereof I hereunto sign my name in presence of twosubscribing witnesses.

PETER MUN ZINGER.
